Amy and Carol Bayer are co-founders of PorchLight Real Estate Group in Denver. The Bayers built PorchLight to be the brokerage they wanted as agents: a full-service outfit that provides agents all the training, coaching, technology and marketing they need. The firm has tweaked the traditional brokerage model with an emphasis on design and in-house technology that increases referrals, improves agents’ productivity and their quality of life.
